Hi
Have just backed a childs quilt with fleece (Windcheater fleece)and put the fluffy side out and I am really delight with the finished quilt my great niece should feel lovely and cosy..a number of my friends have used polar fleece as backing of their quilts and all have workd well..I know I put a lot of pins in the quilt and stitched from the centre out..
see if you can purchase a less stretchy fleece might do the trick, have another go
